Joe Viturello, a vice president at PernaFrederick, brokered both agreements. At 1608 Walnut, he represented the private investment partnership that owns the 19-story 232,000 square foot building in extending the lease with Steel Doebley & Glassman, P.C., that occupies 5,533 square feet on the 15th floor. The renewal will continue that occupancy into the next decade, Viturello said.

At The Philadelphia Building, 1315 Walnut, Viturello represented Powers & Company, a national consulting firm specializing in the preservation and rehabilitation of historic structures, in the extension of its lease for approximately 1,448 square feet on the 17th floor of the 198,000 square foot 18-story structure.

Goldman Properties, managing agent for the building, cooperated with PernaFrederick and represented building ownership in negotiating the renewal agreement that will extend Powers presence at that location to beyond 2020.
